Summary
We propose to supersede Airworthiness Directive (AD) 2005-12- 16, for all Fokker Services B.V. Model F28 Mark 0100 airplanes. AD 2005-12-16 requires an inspection to determine the part number of the passenger service unit (PSU) panels for the PSU modification status, and corrective actions if applicable. Since we issued AD 2005-12-16, we have determined that the required modification actions might not have been implemented correctly. This proposed AD would require an inspection of the PSU panels and the PSU panel/airplane interface connectors for discrepancies, and corrective actions if necessary. This proposed AD would also remove airplanes from the applicability. We are proposing this AD to address the unsafe condition on these products.
